Aspring 17 serves normally to maintain the handles spaced apart as shownin full lines in Fig. l. When the handles are moved to the relativeposition shown by the dotted lines in Fig. 1, the jaws 10 and 1l willengage, and the slots in the jaw 11 will register with the slots in thejawJ 10. When in this position the wire 16 may be inserted in the properslot depending upon the size l of the wire. When the pressure is thenreleased on the handle 7 and the spring 17 causes these handles 7 and 8to separate farther, the slots in the jaws will move out of alignmentand thus the wire 16 will be clamped securely in position, l5 the spring17 beingof suillcient tension to eiIect the proper binding or clamping.It will bevnoted that the smallereslots are positioned closer to thepoint oi pivot so that the smaller wire when clamped by the jaws will bein the slots closer I) to the pivot. This is formed in this manner sothat less strain will be exerted upon the smaller wire than on thelarger wire. v

3 Claims.

My invention relates to a new and useful improvement in a welding tongand has for its object the provision of a tong which will easily andquickly grip a wire strip and securely hold the 5 same in position whileat the same time permitting a ready and /easy movement of the wire tofeed the same w ge being used.l

Another object oi' the invention is the provision o1 a welding tonghaving a pair of col0 operating jaws pivotally connected and having wirereceiving slots formed on corresponding sides which will serve, whenspread apart, for securely clamping a wire which may be placed in theslots when the jaws are in position for l5 aligning these slots.

Another object of the invention is the provision in a'welding tong o f apair of slot bearing cooperating jaws constructed of suiilcient width sothat as the jaws become worn, the slots may be formed inwardly deeperand thus the lite oi! the tong prolonged.

Another object of the invention is the provision in a welding tong o!this class of a simple and etl'ective means for binding the feed wire orelectrode in pomtion. t

Another object of the invention is the provision in a weldingl tong ofan insulated handle so con, structed and arranged as to be light, easilyhandled, highly emcient in use and easily and quickly assembled. j l

Other objects will appear hereinafter.

The a0handleisinsertedintothesocketandis securely iixed by welding or in anyother suitable manner. The feed wire 24 is inserted into the bore 25 ofthe tube 20. Cut from this tube 20 isan oval shaped plate 26 which isalso curved 8l itransversely, and threading through which is a screw 27which projects through the tube 20 diametrically'opposite to the opening28. This construction is such that upon threading o! the screw 27, theplate 26 may be brought into 40 clamping relation with the feed wire 24and securely bind it against the tube 20. The handle 8 is ofcourseformed from conducting material and its jaw 10 is preferably formedintegral therewith.

In the use of a welding tong of this nature, it-

has been found that the molten material or weld will sometimes sputterand strike upon the welding tong and there adhere. This results in apitting or a wearing of the tong, and an undesirable accumulation offoreign material on the tong. Itis my purpose to so treat the tong as toprevent the accumulation of molten material on the tong. The handles 'Iand 8 after fabrication are heated to approximately @ge lhundred degreesand are then immersed in a heavy solution of creosote and there left tocool. The heating must be suilicient to open the pores of the metal topermit the creosote to enter the same. When thus treated, the weld ormolten material will not adhere to the tong with` the result thatgreater life of the tong is effected and more eiiicient workwhile usingthe tong becomes While I have illustrated and described the lpreferredform of construction of my invention, I do not wish to limit myself tothe precise details of structure shown, but desire to avail myself ofsuch variations and modifications as may come within the scope of theappended claims.

Having thus described)my invention, what yI claim as new and desire tosecure by Letters Patent is:. l

1. A welding tong of the clsescribed, comprising; a pair of pivotallymounted handles, each of said handles terminating in a at, comparativelywide and comparatively thin jaw, there being-formed in one of the sidefaces of each of said jaws a plurality of open slots, said slots beinginclined to the planal faces of said jaws and adapted, upon movement ofsaid jaws into lapproached relation, for registering with each other,the slots in said jaws, upon spreading of said jaws, proving out ofregistration with each other.

2. A welding tongof the class described, comprising a pair of pivotallymounted handles, each of said handles terminating in a fiat,comparatively wide and comparatively thin jaw, there being formed in oneof the side faces of each of said jaws a plurality of open slots, saidslots of said handles terminating in a flat, comparatively wide andcomparatively thin jaw, there 'being formed in one of the side faces ofeach JOSEPH VILLARS.
